I'm sad to hear the OG is closing. I'm 51 years old and memories will forever stay in my heart. As a child my family ate there many times , my older sister worked there when I was maybe 1? But I remember eating the taco burger , sitting at the table next to the booth closest to the kitchen and always staring at the small glass "showcase" of different beans I believe . I can still picture how it looked way back then. Aww this is sad. We still enjoy the number 4 and the burrada at the 13th and wads location but the Federal location will forever hold the best memories for me.
